[0027]Specific implementation method: when the main body of the power supply is energized and running, the short-circuit protection mechanism works, the live wire L transmits the current to the fuse F1, and then the fuse F1 transmits the current to the rectifier transformer L1, and then the rectifier transformer L1 transmits the current to the rectifier transformer L2 and Capacitor CX1, then the rectifier transformer L2 sends the current to the rectifier U, and then the rectifier U sends the current to the main body of the power supply. When the main body of the power supply is short-circuited, the rectifier U receives the short-circuit signal and sends an instruction, the capacitor CX1 and capacitor CX2 are disconnected, and the fuse F1 stop working, the design realizes the short circuit protection of the main body of the power supply.
[0028] When the LED lamp L5 works for four hours, the PWM regulator U1M works and sends an instruction, the value of the resistor R6 increase...

Description
technical field [0001] The invention is a power supply for LED lamps with timing power reduction, which belongs to the field of LED lamp power supply equipment. Background technique [0002] LED power supply is a kind of power supply. It is a device that provides power to electronic equipment, also known as a power supply. It is deployed as a different power input on the device connected to an independent circuit device with two or three power inputs. Dry batteries, etc. are also called power supplies; devices that convert alternating current into direct current through transformers and rectifiers are called rectified power supplies. [0003] In the prior art, there is no short-circuit protection mechanism installed in the traditional traditional LED lamp power supply, resulting in that the circuit cannot be automatically shut down and cannot automatically alarm when the circuit is short-circuited, which will easily lead to damage to the main components of the power supply, ...
